SAN MATEO — Police arrested a San Mateo man and two teen boys in connection with arson and graffiti that did an estimated $1,200 damage to Laurel Elementary School, authorities said.

The suspects were arrested after they were spotted allegedly escaping from the campus on 36th Avenue around 4:30 a.m. Monday, police said. Officers found a small fire, which did no structural damage to the school, San Mateo police Sgt. Dave Norris said. It was quickly put out.

Norris said investigators are looking into whether the trio were involved in any of the four recent break-in or vandalism incidents at San Mateo schools over the past month. Police went to Laurel after a neighbor called police.

Norris didn’t name the two 17-year-old San Mateo boys who were arrested on charges that included arson for one teen and trespassing for both. They were both released to their parents.

Norris said the 24-year-old man was Zachary Esswein. He was cited for trespassing and being under the influence of drugs and released, San Mateo County District Attorney Steve Wagstaffe said.
